Air hungry spree's

What makes a spree air hungry? The motors can be strange. Even with different carbs and adjustments, they still eat up the air. My old one actually didnt like much air at all, i am just wondering what to do? Is there a way to adjust this problem? Maybe something to do with the reed valve? I know not to bend it or anything, maybe tighten up the screws in the back?

What is 'air hungry' ?
Are you running rich or lean or what is the problem?

The spree will run fine and everything. It is just that it will be slow as *. (like 5 - 13 max) and thats fast. But when the air box cover is taken off, it will go about 30 mph...

re-clean your a/f

Me and tippmann98 worked on this same project. The air filter made no difference. It still ran slow if it was not sucking all the air in the world in.

To start off, I can tell you what it's NOT - the reed valves.

What it MAY be:
1. Air filter
2. Air inlet box cover plugged?
3. Choke assy not closing all the way when warmed up properly
4. If you are attaching the screw in the middle of the air cover, I had one (truly odd) that collapsed the inlet box when over-tightened.
5. Maladjusted carburetor.

Probably in that order. Does it run good with the cover off AND the filter off? What about if just the cover is on but no filter? Just filter no cover?
Are the two square inlets on the cover plugged with anything? Mud dauber wasps love this area for some reason.

You state that the bike runs alright with the filter and cover on, but slow. Is it missing at all when it's doing this? That would point to rich mix. By taking the air cleaner off, you compensate for the excess fuel going in if it's missing.

This is an interesting one....keep us informed.

Huh. Any chance someone went in and changed the main jet, or the needle position? How do your plug chops look? Are you running really rich with the air filter on (4 stroking, etc.)

If you don't know how to do a plug chop, I'm posting it into the tech docs.

Yes, one of the carbs is over-jetted. That probably explains a little. But, this is the strange part. Even with different carbs, one ot two of our engines is still reluctant and craves mass amounts of air. Its internal i think, my guess is that somebody tampered with the block and widended the intakes.

- Has the case been split? If not then any intake mods were done to the removable bits. Check the intake runner for filing.
- Has the exhaust been drilled/modified/rusted out?
- Has your "good" carb been filed? Some guys will enlarge the "choke" point on the carbs for airflow. Doesn't always work.
- Did you check to see if the "good" carb has an enlarged (drilled) idle jet?

Sounds like you're running rich. Is it any faster with the air filter disconnected? By disconnected, I assume you're still running the rubber tube, but not the filter element (or tube disconnected from airbox.)

No, it all looks in order. It just runs well without the airbox cover off . Its a strange problem. I may type more when i get home

I would just leave well enough alone and leave the airbox cover off or just run a clamp on K&N.

Haha yeah. I was just wanting to make it quieter. I figured it would be more desireable to buy that way.

To make it more desirable to sell, I think you should run down to the nearest Wal*Mart/farm supply and pick up a bagful of $1 yellow marker lights. You could do up the entire undercarriage with a few dozen of those... and yes, I've been drinking.

Lmao, how about some neon lights? lol. I will submit a picture of a blue light under a black spree later on.
